UNITED STATES ALEXANDER KIRKWOOD, OF JACKSON COUNTY, MISSISSIPPI.

IMPROVEMENT IN LOG-CARTS.

Specification forming part of Letters Patent Nof'1`18,460, dated August29, 1871.

To all 'whom 'it may concern:

Be it known that I, ALAXANDER KIRKWooD, of Jackson county and State ofMississippi, have invented certain Improvements in hoisting logs ortimber on timber-Wheels for hauling, of which the following` is aspecification:

My invention relates to the combination of cog-Wheels with aflange-Wheel, levers, grapplechain, log-hooks, and slide, in such amanner as to bring all the Working parts conveniently near together.'

In the accompanying' drawing, Figures l and 2 are views of a machineembodying my invention, and showing all its Working parts.

B B is the aXle; A A, the hounds, the lefthand one of which is cut shortto make more room, and the right hand left longer, in order tocounterbalance the tongue. C C, the frame to which the machine issecured; this frame is firmly bolted to the hounds A A. D, the mainspur-Wheel; E, the main shaft; F, the pinion; G, the pinion shaft; H,the iiange-Wheel, Which is adapted to the holding of four Wood levers;J, the grapple-chain, Which chain is about its middle forked, the upperend dividing into two parts; I I,.the chain-hooks, which are at theupper ends ofthe chain; K K, the loops on the main shaft, into which thechain-hooks fasten; L, the log-hooks; n a n u, the levers, which areattached to the flange-Wheel H by bolts; M, the slide to catch and holdone of the levers u, thereby preventing the log or Weight, when raised,from running` down.

The above-described Wheels should be castiron, and their shaftsWrought-iron, and hung in metal boxes.

To hoist a log or Weight, rst fasten the loghooks L to it. Then, Withthe levers n n n n, turn the flange-Wheel H, which moves the pinion F,turns the main spur-Wheel D, and winds the grapple-chain J on the mainshaft E and, when the log or Weight is up, then move the slide M to theleft hand, and it will catch one of the levers n and prevent the log orWeight from run" ning down.

I do not claim the pinion or spur-Wheels, for they are a Well-knowndevice.

I claim as my invention- The combination of the several parts of thelog-cart, as shown and described.
